Very long interview with a lot of questions that were discussed in depth afterwards. 3 h duration and a lot of drawings. 2 people i discussed with and then hr

broken into 3 stages with 3 different people. First section was a competency-based interview, quite relaxed, next was a innovative solution you had to make up and discuss and the last was a case study and you had to come up with solutions and what you would do.
